Yes, it is not caused by rotation at all!! Gravity is simply the attraction that every object has for every other object. The spinning of the earth actually pulls you away from the earth, so you'd be (very) slightly heavier if the world stopped spinning.
For example, the moon spins very slowly in comparison to the earth, and still has gravity. Because the moon is about 1/6 the mass (mass=amount of matter) of the earth, you weigh (the force with which gravity pulls you) 1/6 what you do on Earth.
You can think of gravity as a weak magnet that will work on anything, not just metal. The force of gravity is related only to the mass of the two objects and the distance between them:
F = G*Ma*Mb / r^2. G is a constant, Ma and Mb are the masses of the objects--you and the earth, and r is the distance between them. (Note that r is squared, so as you get further away, F (force) gets smaller really fast).

Speed of Earth's Rotation Slowing?
The Earth's spin is slowing down by about 1.5 - 2 milliseconds per century, and that angular momentum is moving into the Moon's orbit, which is getting larger. The reason for this, and the reason a figure skater can only spin for so long, is friction. In the case of the skater, it's air resistance and friction with the ice. In the case of the Earth, it's the friction due to tides moving around the Earth.
What Happens if Earth Stops Rotating?
Of course, this can't happen, but if it did, everything not attached would go flying off to the east, parallel to the surface of the Earth. The speed would depend upon your latitude. Only the people at the poles would be safe. You wouldn't go flying off into space because the 1000 mph maximum (at the equator) isn't enough to overcome gravity, which would still be present. If you survived, the resulting six month day and six month night would probably take care of you pretty quick.
Earth's Orbit
The Earth's orbit varies from 0.983 AU out to 1.067 AU. We are actually closer to the Sun in the winter than in the summer. The orbit crosses the 1 AU point two times a year - in spring and fall
Jump!
The mass of all the people on Earth is miniscule compared to the mass of the Earth, so neither of these actions would have any effect on Earth's motion.

Gravity is caused by mass and only mass.
Every mass in the universe is attracted to every other mass in the universe.
If the Earth stopped spinning, Earth's gravitational influence would remain the same.
But while the Earth was spinning, all the objects on the surface were experiencing centripetal acceleration....and what was supplying this centripetal acceleration?....Gravity!
When the Earth stops spinning, we stop accelerating centripetally. Because of this, we "feel" slightly heavier, not a lot, just slightly. The amount of our increase in weight will depend on our location in the surface of Earth since the centripetal force experienced is not constant across the surface. Those on the equator would feel the greatest increase in weight, those on the geographic north and south poles (the axis of rotation) would feel nothing since they were never centripetally accelerating.
There is NO such thing as "Centrifugal force".

Since gravity is caused by the MASS of the earth. The rotation has nothing to do with it. So yes, you would still be pulled to the Earth if it stopped spinning.
Since we are normally traveling up to 1000 miles per hour (at the equator) we would actually weigh more if the Earth stopped spinning.

There's a small centrifugal force due to the earth's rotation around it's axis like when you ride one of those platforms that spin around at the play ground. So when the earth stopped spinning on it's axis, you would weigh the most if you were standing somewhere perpendicular to it's axis rather than at the poles of the axis where there would be essentially no change.

The spinning has nothing to do with gravity If the earth stops spinning. Were the earth to stop spinning, we would be stuck here more firmly than ever. That's because, due to the lack of centrifugal force, you would weigh more. And Just so you know the speed of the earths spin has slowed over time and continues to as the moon moves farther away

the nice and cozy molten metallic in the outter middle is spinning. This spinning warm metallic creates the magnetic container. If stopped spinning on that's very own or due the Earth ceasing to spin it may no longer create the magnet container. Gravity could nonetheless artwork as that's purely a function of mass and distance. The moon nonetheless has gravity yet has no magnetic container with the aid of fact it has no molten middle.

you would be even more pulled to the earth if the earth stopped spinning. See, spinning creates centrifugal force, which pulls matter out from the center of rotation. this acts as an opposing force to the gravity that mass creates.

If the Earth stops, you can stay over it because the gravity no depends of spinning of the Earth

So long as the Earth stopped spinning slowly and didn't just come to a sudden stop (that would kill us all) yes we would still be stuck to the Earth. The sudden stop would fling everything eastward at around 900 mph, that would be bad!
